The purpose of the present study lied in examining the incidence, treatment and failure causes of peri-implantitis by analyzing medical charts of those patients who underwent implant placement for the past 2 years. The subjects included those patients who underwent implant placement at the present hospital from January 2001 to December 2002. 3i implants were used for the analysis for the comparison of significance. A total of 301 patients were examined, among whom 102 were females and 199, males. Implants were placed in a total of 578 cases. The number of peri-implantitis was present in a total of 29 cases (21 males and 8 females), giving the incidence at 9.6%. The evidence of peri-implantitis was seen in 60 cases, which was in 10.4% of the patients. Among those cases with peri-implantitis, 28 cases (47%) underwent bone graft and 22 cases (43%) underwent maxillary sinus lift. Furthermore, 4 of these patients had systemic diseases such as diabetes or hypertension. Regular management is important for the preven ion of peri-implantitis. In other words, early prevention through regular follow-ups to check the status of surrounding soft tissue would be needed to maintain implants.

BACKGROUND: Nitric Oxide (NO) has been discovered to be an important endothelium-derived relaxing factor. The exogenous inhaled NO may diffuse from the alveoli to pulmonary vascular smooth muscle and produce pulmonary vasodilation, but any NO that diffuses into blood will be inactivated before it can produce systemic effects. To examine the effects of NO on pulmonary and systemic hemodynamics, NO was inhaled by experimental dogs in an attempt to reduce the increase in pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) induced by hypoxia in dogs. METHODS: Eight mongrel dogs were studied while inhaling 1)50% O2 (baseline), 2)12% O2 in N2 (hypoxia), 3)followed by the same hypoxic gas mixture of O2 and N2 containing 20, 40 and 80 ppm of NO, respectively. RESULTS: Breathing at FIO2 0.12 nearly doubled the pulmonary vascular resistance from 173 56dyn sec cm-5 to 407 139dyn sec cm-5 and significantly increased the mean pulmonary artery pressure from 16 3mmHg to 22 4mmHg. After adding 20~80 ppm NO to the inspired gas while maintaining the FIO2 at 0.12, the mean pulmonary artery pressure decreased (p<0.05) to the level when breathing oxygen at FIO2 0.5 while the PaO2 and PaCO2 were unchanged. The pulmonary vascular resistance decreased significantly and the right ventricular stroke work index returned to a level similar to breathing at FIO2 0.5 by addition of NO into the breathing circuit. Pulmonary hypertension resumed within 3~5 minutes of ceasing NO inhalation. In none of our studies did inhaling NO produce systemic hypotension and elevate methemoglobin levels. CONCLUSIONS: Inhalation of 20~80 ppm NO selectively induced pulmonary vasodilation and reversed hypoxic pulmonary vasoconstriction without causing systemic vasodilation and bronchodilation. Methemoglobin and NO2 were within normal limit during the study.

3.Predictive Model for Quality of Life of the Older Men Living Alone
Journal of Korean Academy of Nursing 2020;50(6):799-812
Purpose:
This study aimed to construct and test a predictive model that explains and predicts the quality of life in older men living alone.
Methods:
A self-report questionnaire was used to collect data from 334 older adult men living along aged 65 years or over living in Jeollanam-do provinces. The endogenous variables were depression, self-rated health, instrumental activity of daily life, health promotion behaviors, the number of social participation activities and quality of life. Data were analyzed using the SPSS 21.0 and AMOS 21.0 programs.
Results:
The final model with 14 of the 8 analysed paths showed a good fit to the empirical data: χ2= 173.26(p < .001, df = 53),normed χ2= 3.27, GFI = .92, NFI = .90, CFI = .93, TLI = .89, RMSEA = .08 and SRMR = .06. Activities had direct effect on quality of life of older men living alone and social support had both direct and indirect effects. Meanwhile, function and socioeconomic status showed only indirect effects.The variables included in the eight significant paths explained 83.7% of variance in the prediction model.
Conclusion
Instrumental activities of daily living and social support effect directly on quality of life in the older men living alone. Findings suggest that health care providers including community nurses need to provide social support as well as empowerment programs of instrumental activities of daily living and health promotion for improving quality of life of the older men living alone.

Severe sepsis and septic shock are the main causes of death in critically ill patients. Early detection and appropriate treatment according to guidelines are crucial for achieving favorable outcomes. Endotoxin is considered to be a main element in the pathogenic induction of gram-negative bacterial sepsis. Polymyxin B hemoperfusion can remove endotoxin and is reported to improve clinical outcomes in patients with intra-abdominal septic shock, but its clinical efficacy for pneumonic septic shock remains unclear. Here, we report a case of a 51-year-old man with pneumonic septic shock caused by Pseudomonas aeruginosa, who recovered through polymyxin B hemoperfusion.

BP201, porcine lung tissue-derived phospholipids, consists of phosphatidylcholine as a major phospholipid species. BP201 promoted hair growth after application onto the shaved backs of BALB/c and C3H mice. Its effect was enhanced when applied together with minoxidil (MNX) in C3H mice. When the tissue specimens prepared from the shaved skins of BP201-treated and control mice were microscopically examined, the total numbers of hair follicles in both anagen and telogen phases of BP201-treated mice were significantly higher than those of control mice. The numbers of hair follicles in the anagen phase of BP201-treated mice were also higher than those of control mice. In combination with MNX, BP201 further increased the total number of hair follicles, but did not alter the percentage of hair follicles in the anagenic phase. BP201 also increased the proliferation of human hair follicle dermal papilla cells. Collectively, BP201 possesses hair growth promoting potential, which would suggest its use singly or in combination for hair growth products.

Ischemic preconditioning (IP), short pre-treatment sublethal ischemia, induces a state of protection against subsequent prolonged ischemia-reperfusion. The purpose of this study was to investigate the expression of HO-1, HSP70, and iNOS proteins in the liver subjected to the courses of reperfusion after repetitive cycles of remote IP in the rat. Using thirty five week-old rats, the remote preconditioning was undertaken by vascular clamp occlusion of blood flow to one hindlimb, with 3 and 10 cycles of 5 minutes occlusion followed by 5 minutes reperfusion. The liver was removed 0, 3, 6, 24, and 72 hours of reperfusion after remote IP and assayed by immunohistochemical staining and Western blotting analyses for anti-HO-1, anti-HSP70, and anti-iNOS antibodies. The expression of HO-1 in rat liver increased at 72 hours of reperfusion groups after 3 and 10 cycles of remote IP, compared with normal control groups. The expression of HSP70 in rat liver increased at 6 hours of reperfusion groups after 3 cycles of remote IP, compared with normal control groups. The expression of HSP70 in rat liver increased at 0 hour of reperfusion groups after 10 cycles of remote IP, compared with normal control groups and decreased at 24 and 72 hours of reperfusion groups. The expression of iNOS in rat liver increased at 24 hours of reperfusion groups, but decreased at 72 hours of reperfusion groups after 3 and 10 cycles of remote IP, compared with normal control groups. In summary, these results showed that at early phase of reperfusion after remote IP, HSP70 expression was increased in rat liver. However, at 72 hrs of reperfusion after remote IP, HO-1 expression was increased and iNOS expression was decreased in rat liver.

Malignant hyperthermia is a recently described and drmatic syndrome which rarely occurs during anesthesia, but when & dose occur is still fatal in the majority of cases with unknown etiology. It si a rypermetabolic condition characterized by tachycardia, tachypnea, skeletal muscle rigidity, respiratory and metabolic acidosis and cyanosis etc. A case is presented of a 20 year old gerveralcy healthy female with a family history of congenital eye-ild ptosis in herself as well as in all her brothers and sisters( male 2, female 4) and a generalized muscle weakness of unknown origin for several years in her father. She underwent a minor operation for correction of the congenital eyelid ptosis under N2O-O2-tachycardia developed followed by severe arrhythmia with unstable BP, minutes after induction tachycardia developed followed by sever arrhythmia with unstable BP, muscle rigiditiy and hyperpyrexia. 15 minutes after induction anesthesia was stopped and aggressive emergency treatment was atlemted. Unfortunately, she died postoperatively on the 8th day after anesthesia. Possible etiologic factors, the clinical features and management of malignant hyperthermia are discussed.

BACKGROUND: Clonidine, an 2-adrenergic agonist, shows the analgesic effect and potentiates the analgesic effect of opioid. However, when it is injected with bolus technique, it reveals the short duration of inadequate analgesia and induces hypotension, bradycardia or sedation. We examined the analgesic and side effects of clonidine administered by continuous epidural infusion over 24 hrs, following epidural morphine injection. METHODS: Sixty parturients, scheduled for elective cesarean section under epidural anesthesia were randomly allocated into three groups. They received an infusion of saline alone (group 1, n= 20), clonidine 20 g/hr (group 2, n= 20), or 40 g/hr (group 3, n= 20) respectively, following epidural morphine 3 mg injection at the end of operation. The total doses and number of request for supplemental analgesic, blood pressure, heart rate, and degree of sedation were measured during 24 hrs. RESULTS: There were significant differences in pain relief between clonidine groups and group 1. The total doses and number of patient's request for supplemental analgesic in clonidine groups, compared to group 1 were significantly decreased (p<0.05), but no significant differences between the two clonidine groups. The diastolic pressure of group 3 was significantly lower than that of group 1 over 24 hrs, and that of group 2 at 18 hr, 24 hr (p<0.05). However, there was no severe hypotension, bradycardia or sedation in the three groups. CONCLUSION: Clonidine administered by continuous epidural infusion over 24 hrs enhances the analgesic effect of epidural morphine, and the infusion of clonidine with 20 g/hr rather than 40 g/hr shows minimal changes of blood pressure. Therefore, administration of epidural clonidine (20 g/hr) following epidural morphine may be considered as a regimen for pain management after cesarean section.
